How could we simplify the problem into something implementable?
I started thinking of something easily-appliable and started experiencing suffering instead of excitement :( I was thinking that strong random number generators are usually generated based on randomness metrics, so if you saw low randomness in the output it might indicate destructive interference between the user data and the random number generator. I'm curious whether that's true or not. I'm guessing it's not actually true. I imagine cryptographers would know, but I'd like to check in some way. Anyway, I think there is probably some way to simplify it. Like, say we had a _super simple random process_ ... or a _simplistically vulnerable random process_, like a gaussian distribution or something .... or a _simplistically biased random process_ like 0 90% 1 10% ... any of these would be reasonable. Maybe the simplistic bias? To keep things kinda noisy but also useful? Then, um, uh, for the user text, we could use GPT2 ? Or .... I dunno! How about GPT2?
